HINGE Filed April 14. 1950 Patented July 19, 1932 UNIT STATES PATENT i v ERNEST A. ARNDT, OF SIOUX CITY, IOWA, ASSIGNOR TO THE GABRIEL KARLKEEN COMPANY, OF SIOUX CITY, IOWA, A CORPORATION 01T DELAWARE HINGEl Application filed April 14,

My invention relates to the hinge and has for its object to provide a hinge that is particularly adapted to be used for connecting the members of a sheet metal trunk or the like.

More particularly it is my object to provide a hinge of exceedingly sturdy construction and yet simple and inexpensive to produce. v

A further object is to provide a hinge in combination with the walls of a receptacle such as a sheet metal trunk which can be easily and quickly assembled.

Another object is to provide a hinge structure in combination with the walls of a receptacle, the hinge structure being adapted to exclude to a large extent dust and moisture from the interior of the receptacle.

A further object is to provide a hinge which is particularly adapted to support the strain imparted to the horizontal wall, the movable member of a combination trunk and luggage carrier when loaded. f

A further object is to provide a hinge which is pleasing to the eye in addition to being strong, simple and otherwise advantageous as above noted.

lith these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of a combination trunk and luggage carrier embodying the hinge construction of my invention.

Fig. 2 is a plan view of the hinge enlarged.

Fig. 3 is a detail, sectional view taken on the line 3 3 of Fig. 1.

Fig. 4 is a detail, sectional view taken on the line At--t'of Fig. 1.

Fig. 5 is a detail, sectional view similar to Fig. 3 with the trunk members in relatively closed positions.

The type of trunk for which my hinge has been primarily intended is that wherein a iixed trunk member A of sheet metal is rigidly supported on the rear 0f a vehicle and a 1930. serieu 110.444,'021.

member A a closed trunk toa positionV where- 7 in it cooperates with a fixed trunk member A to form an open top luggage carrier as shown in Fig. 1. y I

lIhe walls of the respective members A and B which form the bottom of the open luggage carrier are indicated by the reference charactors 10 and 11, respectively. These walls are hinged together. rl`he side walls 12 and 3 of the fixed vand movable trunk members, respectively, are provided with coacting devices 14, which limit the outward swinging movement of the movable trunk member to a substantially horizontal position; These coacting members support the weight kof the luggage carried by the luggage carrier.

It will now be seen that the function of the hinge between the walls'rlO and 11 are several, as follows: to support the adjacent region of the vwall 11 against thelload pulling directly downward thereon; toreceive an end thrust of the wall 11 caused'by the weight of the luggage in the movable member B pulling downwardly against the outer'extremity of the member Band tending to swine it about an axis deiinedby'the engagementof the elements 14 near the upperfends of the walls 12 and 13; to form a weathertight connection between the walls'lO and 11 when the trunk is open 5: cand to allow hinging movement of the member B* to an upstanding position at rghtangles to the one showninFig. 1. l y

r1`he wall 11 is provided with a `plurality of spaced slots 15. which vform between them:

a plurality of spaced tongues 16y (see Fig. 8). The tongues lrare bentbaclr beneath the wall 10 to forni a plurality of hinge-'sleeves The metal of the 15 is pressed upwardly to `form a series of hoods 18, which are connected to the sleeves 17 as at 19 by the corner portions of extruded metal. It may now be noted thatv theslot's 15 extend only part `way through the hinge wall 10A adjacent the slots sleeves 17, the hoods 18 forming enlarged continuations of the sleeves.

The bottom Wall 11 of the member B is provided with a series of hinge hooks 20, which substantially lill the slots 15 from side to side and which are riveted or welded to the wall 11 as at 21. The hooks y2O are provided with Hat Shanks 22, which are received between the wall 11 and a false bottom 23 and spot welded or riveted therebe-v tween. The hook portion of'each hook 20 terminates in an end portion 24, which is perpendicular to the plane of the shank 22 and terminates in the plane of the lower face thereof. The terminal portions 24 of the hooks thus will rest in flat contact with the bottom wall 11, as shown in Fig. 3.

The wall 11 serves to close the open side of the hook to form a hinge loop. A reinforcing band 25 extends from side toside of the movable trunk member B and its riveted or spot welded to the lower face of the wall 11 by the same means which secures the hinge loops in place.

It may now be noted that the wall 11 extends beneath the inner extremities of the slots 15, a serving in conjunction with the hooks 2O to close the slots from below. The extended portion of the wall 11 will contact snugly with the underturned tongues 16 be tween the slots 15 to tightly close the regions between the slots. The hooks 20 engaging both the wall 11 and the hoods 18 as shown in Fig. 3 and substantially filling the slots 15 from side to side serve to close the spaces formed by the slots 15 between the wall 11 and the hoods 18.

p A hinge pin 30 extends through the hinge loops 17 and hooks 20 and completes the hinge. n

In assembling the trunk, the hooks 2O may be inserted between the walls 11 and 23 and held there by friction whilethe member B is fitted to the member A and then adjusted to the exact positions necessary to register snugly in the slots 15. A hinge pin may then be inserted and the welding or riveting accomplished with the hinge assembled. The process is very simple and eliminates error.

Downward pressure on the bottom 11 will be transmitted through the rigidly associated hooks 2O to the hinge pin 30. In this connection, it will be noted that the hook 20 opens downwardly and downward pressure will be transmitted from the crown portions of the hooks to the hinge pin.

End pressure of the wall 11 will be transmitted through the hooks 20 to the hoods 18, with which they are in contact.

Since the hinge loops formed by the hinge 20 are displaced upwardly from the bottom of the member B, the latter will be allowed to fold upwardly to a vertical position as shown in Fig. 5, in which position the wall 23 will closely approach the edges of the hoods 18.

It will be understood that the hinge cond struction of my invention may be applied to other constructions than the particular type of trunk or receptacle shown herewith. The main advantages. of the invention are found, however, in a construction where strength, simplicity and weather-tight qualities are required.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
